Key Features

HI8614N pH Transmitter is a water-resistant process instrument designed for accurate long-distance pH monitoring in industrial applications, featuring a 4-20 mA isolated analog output and robust signal amplification.

Enables reliable pH measurement from 0.00 to 14.00 pH with high input impedance.
Features galvanically isolated 4-20 mA analog output, ensuring signal stability even over long cable runs.
Compatible with standard high impedance pH probes with BNC connectors for flexible integration.
Provides fast, accurate readings with fixed or automatic temperature compensation up to 100°C using the HI76608 probe.
Industrial-grade water-resistant IP65 housing ensures durability in demanding field environments.
Offers offset calibration ±2 pH (±2.2 mA) and slope calibration 86 to 116% (±0.5 mA) for precise maintenance.
Suitable for process control in water treatment, manufacturing, and laboratory automation setups.
No local LCD display (see HI8614LN for version with display), reducing on-site adjustment errors.
Operates on 18–30 VDC supply and maintains stable output across varying load and cable capacitance conditions.

Product Description

The Hanna HI8614N pH Transmitter with 4-20 mA galvanically isolated output is engineered for precise and long-distance measurement of pH in industrial process control systems. Designed to work with a standard high impedance pH probe (BNC connector), this transmitter features a special high impedance amplifier and robust water-resistant enclosure conforming to IP65 standards, making it ideal for harsh field environments.

Supports accurate pH readings from 0.00 to 14.00 pH with high input impedance (10¹² Ohm), enabling compatibility with various pH electrodes.
Galvanically isolated 4-20 mA analog output provides superior noise immunity and reliability for transmission over extended cable distances.
Fixed or automatic temperature compensation (0–100°C) ensures rapid, stable, and accurate measurement even with fluctuating sample temperatures, when used with HI76608 probe.
Industrial-grade offset and slope calibration, including offset adjustment ±2 pH (±2.2 mA) and slope range from 86 to 116% (±0.5 mA), facilitate routine recalibration and maintenance.
Water-resistant IP65 housing ensures the transmitter stands up to dust, spray, and humidity, making it suitable for continuous deployment in process control or water treatment plants.
Power requirements of 18–30 VDC (HI8614N) allow convenient compatibility with common industrial power supplies.
No onboard LCD display eliminates on-site tampering and reduces points of failure (for version with display, refer to HI8614LN).
Can be used in manufacturing plants, laboratories, wastewater treatment facilities, water purification systems, and other demanding environments requiring accurate pH monitoring and control.

Dimensions: 165 x 110 x 71 mm; Weight: 1 kg. The device accepts pH electrodes via BNC, includes IP65 protection, and supports a relative humidity of up to 95% non-condensing in temperatures from 0 to 50°C.
